The Gaia-ESO survey: 3D NLTE abundances in the open cluster NGC 2420 suggest atomic diffusion and turbulent mixing are at the origin of chemical abundance variations
(European Southern Observatory, 2020)
Context. Atomic diffusion and mixing processes in stellar interiors influence the structure and the surface composition of stars. Some of these processes cannot yet be modelled from the first principles, and they require ...
High resolution HDS/SUBARU chemical abundances of the young stellar cluster Palomar 1
(2011)
Context. Palomar 1 is a peculiar globular cluster (GC). It is the youngest Galactic GC and it has been tentatively associated to several of the substructures recently discovered in the Milky Way (MW), including the Canis ...
Mild evolution of the stellar metallicity gradients of disc galaxies
(2017)
Context. The metallicity gradients of the stellar populations in disc galaxies and their evolution store relevant information on the disc formation history and on those processes which could mix stars a posteriori, such ...
SELECTED TOPICS IN THE EVOLUTION OF LOW-MASS STARS
(S/EDITORIAL, 2013)
Low-mass stars play a key role in many different areas of astrophysics. In this
article, I provide a brief overview of the evolution of low-mass stars, and discuss some of
the uncertainties and problems currently affecting ...
